That’s sort of what happened to the group Americans Elect, a nonprofit launched to place a centrist, nonpartisan presidential candidate on the ballot in all 50 states. On Thursday, the group announced it was giving up. Nobody had come close to meeting the minimal threshold of 10,000 votes to win the Americans Elect primary, held online.

Clearly the United States just isn’t ready for a third party, some analysts opined.

“The failure of the effort is notable because of its place in history,” wrote Aaron Blake in The Washington Post’s Fix blog. “This is, after all, a time of historic unhappiness with Congress, and if there was ever an opening for such an effort, 2012 might have been the year to get it done.”

“Instead, it appears the third-party renaissance in American politics will continue to be put off,” he concluded.

But maybe it’s not that America isn’t ready for a third-party presidential candidate. After all, when the right person has come along – someone like Ross Perot in 1992 – he has been able to win a significant chunk of votes and arguably swing the outcome of an election. If Mr. Perot hadn’t flaked off in the middle of the campaign, dropping out temporarily, it’s possible he could have even won.

The difference with Perot (and Ralph Nader, John Anderson, Theodore Roosevelt, and all the others in the “third party” club) is that the candidate came first, and the money and organization followed. What Americans Elect was trying to do was the reverse – build an organization and handle the tedious task of getting the party on the ballot in all 50 states. It was like the “Field of Dreams” of American politics: Build it and they will come.

There’s also no denying that the United States political system – with a Congress and not a parliament, a president and not a prime minister – is rigidly two party. Elections are winner take all in single-member districts, without all the coalition-building that comes with a parliamentary setup. So voters are, for the most part, forced into two camps.

Sure, there are lots of small “third parties” out there, but they rarely win major elections. The few political “independents” in Congress – like Sen. Bernie Sanders of Vermont – are people who get elected not because of some structure someone else set up, but through their own political skill. And they end up caucusing with one party or the other anyway (in Senator Sanders’s case, the Democrats).

Another factor that might have dampened enthusiasm among major players for running via Americans Elect is the all-out nastiness involved in a presidential campaign. No one should underestimate how hard it is to run for president – not just for the candidate but also for his or her family.

So it may be that an effort like Americans Elect could work sometime in the future. There just needs to be someone reasonably high profile, with obvious political chops, willing to take that leap as a candidate.
